ELEVATING DEVICE FOR HAY AND GRAIN STACKERS.

SPECIFICATION forming part of Letters Patent No. 415,900, dated November 26, 1889.

Application filed March 12, 1889. Serial No. 303,055. (No model.)

Grain Stackers, of which the following is a full, clear, and exact description.

My invention relates to an improvement in elevating devices for hay and grain stacker-s,

and has for its object to provide a device capable of being conveniently and expeditiously attached to or detached from a stacker; and a further object of the invention is to provide an elevating device of simple and durable construction.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanyiug drawings, forming a part ofthis specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the device in place upon a stacker. Fig. 2 is a perspective view of the elevating and carrying frame and one section of a stacker. Fig. 3 is a perspective view ofthe carrier, illustrating the same in the dumping position; and Fig. 4 is a side elevation of the carrier when in position to be carried up above the stacker.

A represents a knockdown stacker-frame formed of a series of upper and lower sections to a. The upper and lower ends of the lower sections a have secured thereto connecting-straps '11 and 12, respectively, the ends of which may be connected in any suitable way. The upper ends of the upper sections are connected also by suitable straps 19, and their lower ends are hinged to the upper straps of the lower sections.

As the stacker-frame forms no part of the present invention it will not be described in detail.

I will now describe my improved elevator. At opposite sides of the body a shoe 30 is rigidly secured to the upper strap of the lower section, in which shoe the downwardly-exten ding and flattened end 31 of the trunnion 32 is slid, whereby a trunnion is held to project outward from opposite sides of the completed body, as best shown in Fig. 9, in which the trunnion is illustrated as applied to one section and detached from the opposite section. Upon each of the trunnions a hub 33 is loosely mounted, provided with three spaced arms 34, 35, and 36, radiating from the upper surface. A rod or bar 37 is rigidly secured in each of the hub-arms 3i, which rods are carried forward beyond the front of the body of the device and securely attached, respectively, to opposite sides of the box-like carrier 38. The carrier 38 is provided with a hinged inner side The pintle or spindle upon which the lower end of the said drop side of the carrier is hinged is projected upward beyond the edges of the said side, and one extremity of the pintle is bent at a right angle to the body, as best illustrated at 41 in Figs. 3 and r. This crank-arm ll is adapted for contact with a spring 42, rigidly secured at one end to the carrier 38, and extending transversely, essentially, from side to side, as shown in the same figures.

Upon the opposite projecting end of the pintle 40 a disk 43 is rigidly attached, provided with a peripheral or cam lug 4 1, and upon the end of the carrier at which the said disk is located a spring 455 is secured at the upper end, which spring curves inward and downward, and is provided between its ends with an imvardly-projecting lip 45, capable of normally engaging with the lug T4: of the disk, as shown in Fig. 2. \Vhen the spring 45 is thus in contact with the disk 43, the drop side 39 of the carrier 38 is held in the upper or closed position illustrated in the said Fig. 7, and when the spring 45 has been dropped so as to release the disk 43 the side 39 is free to drop down until the crank-arm 41 comes in contact with the springs 42. The said drop side may be carried farther downward by exerting pressure thereon, and when said pressure is removed the spring 43, acting upon the crank-arm 4:1, throws the drop side 39 upward to a locked position again, whereupon the disk &3 is once more brought in contact with the spring 45, and the hinged side of the carrier is held in a closed position. hen in this position the carrier receives its lead.

A bar 46 is curved over the device, the ends of which bar are respectively attached to the several hubarms 35, and a similarly-curved bar 47 is made to connect with the hub-arms 36. The two curved bars 46 and 47 are united at their center by a preferably curved guidetrough 48, the ends of which trough are ordinarily open. To the forward end of the bottom of the trough a rope 49 is rigidly attached, which rope is passed through the trough in contact with the bottom over the body of the device and downward to a point at the rear of the same, as best illustrated in Fig. 1.

In front of the device, to one of the slats or bars of one of the upper sections a, a vertical trip-post 50 is rigidly secured, adapted for the manipulation of the carrying-frame heretofore described, to release the spring 45 from contact with the disk 43, and from opposite sides of the body, to the rear of each of the trunliions 32, a spring-arm 51 is secured to the upper strap 11 of one of the lower sections a, which spring extends outward at a right angle to the body, as illustrated in Fig. 1.

In the operation of the device, the carryingframe or carrier being in the position illustrated in positive lines in Fig. 1,the material to be stacked or confined Within the body of the device is placed in the carrier 38. hen said carrier has been filled, the operator draws upon the rope 49, whereupon the carrier is elevated to the open top of the body. As the spring 45 engages with the trip-post 50 it is pushed forward, and the lip 45 is carried out of contact with the lug 44 of the disk 43, and the weight of the material in the carrier forces downward the side 39, which is now over the opening in the top of the body, and the said material thereby escapes from the carrier into the body. As soon as the carrier has emptied itself the spring 42, acting upon the crank-arm 41, forces the dropped side 39 upward again to a closed position, and the disk 43 is once more brought in contact with the spring 45. The frame is pulled farther rearward until the rear bar or rod 47 of the frame contacts violently with the horizontal member of the body-spring 51, as shown in dotted lines in Fig. 1, whereby the said memher is depressed, and upon the recoil of the said member of the spring the entire frame is thrown forward to the position shown in positive lines in Fig. 1 to receive another load; and in this manner the operation is repeated until the entire body has been filled or as much placed therein as may be desired.

Having thus described my invention I claim as new and desire to secure byLetters Patent- 1. In an elevating device for hay and grain stackers, the combination, with the axles, hubs loosely mounted thereon, and an arm radiating from each of the hubs, of a carrier supported by the arms and provided with an inner hinged side, and means, substantially as shown and described, for raising and lowering the carrier, as set forth.

2. In an elevating device for hay and grain stackers, the combination, with the axles or trunnions adapted for attachment to the stacker, a hub loosely mounted upon each axle, and forwardly-extending arms attached to the said hubs, of a carrier supported'by said arms provided with an inner hinged side, a crank-arm fastened to one end of a hinged pintle, a cam-disk secured to the opposite end of said pintle, a spring attached to one end of the carrier capable of engaging the camdisk, and a horizontal spring attached to the opposite end of the carrier capable of contact with the crank-arm, substantially as described.
